For example, over-fishing has caused a disaster for the colony on Rost Island in Norway. In recent years puffin parents have not caught enough fish to feed their chicks. Thousands of chicks have starved. This happened because people drastically depleted the herring stocks. Over-hunting occurs when too many individuals of a particular species are killed and the remaining population is unable to replace losses. Over-hunting puffins for food and feathers caused the loss of puffins from several colonies in Maine such as Eastern Egg Rock.
Mammals such as fox and rats introduced by humans, can be very destructive because the puffins do not have adaptations to avoid them. Puffins choose isolated islands to breed because there are no large predators on the ground to disturb their nesting. If humans introduce mammal predators to these islands, the puffins are very vulnerable and may no longer be able to use that island for breeding.
Also, they become sick when they swallow oil while attempting to clean their feathers. Chemicals from farming that flow from farm to river to ocean can also make puffins sick.
Uncontrolled tourism can be harmful to puffin colonies because they need solitude to breed. People who get too close may scare off parents from their duties of feeding their chick. As long as tourists stay on boats at a safe distance and do not disturb the puffins, they can easily enjoy watching a colony during the nesting season.
While humans have hurt puffin numbers in the past, we also have the ability to restore and protect colonies. We need to reduce pollution of our coasts and do a much better job managing our fisheries. This benefits seabirds and people. Puffins are not endangered but they are threatened by human activities and are rare in many areas where they were once abundant.
As a result, it is important to protect critical puffin breeding and feeding habitat. In some parts of their range there are just a few colonies.
Restoration of former nesting colonies helps to reduce the risk to the regional population by establishing more nesting sites.
Maine puffins were over-hunted by early settlers for food and feathers. The colonies were harvested for the maximum number of birds and eggs that could be taken without thought to whether the colony could support that level of hunting. By the puffins were gone from the Gulf of Maine except for 2 isolated colonies. This was done so the puffins would think Egg Rock was their home and eventually return there to raise their own chicks. From to a total of downy chicks were transplanted into artificial burrows on Egg Rock.
Numbered bands were used to tag the chicks so they could be identified if they returned. In decoy puffins were placed on the island to help attract returning birds. The first puffins returned that summer. In , the first chick was reared on Egg Rock where puffins had been absent for over a century.
A similar project was completed at Seal Island National Wildlife Refuge where puffin chicks were transplanted between — Puffins recolonized Seal Island in They are adapted for preying on fish that live in cold waters. Rising sea levels could hurt puffins by flooding their breeding islands.
Global warming could also affect the distribution of the fish the puffins eat and feed their young. Puffins help people by acting as indicators of ocean health, especially over-fishing. Puffins indicate the abundance of fish by the numbers of fish they bring ashore for their chicks. If over-fishing depletes fish populations then puffins will bring home less fish.
This is a warning that we are over-fishing the ocean. This is bad for puffins and humans, since we both rely on fish for food. Puffins can serve as food for people. Locals of the Faroe Islands, Norway and Iceland have hunted puffins for centuries. The Lofoten people Norway use special puffin dogs to dig birds from burrows among narrow rocks. Puffins swim along the surface of the water and dive to depths of up to 60 metres to hunt for food.
A puffin can hold up to 61 fish in its bill at a time. Globally, Atlantic puffin are considered a vulnerable species with a decreasing population trend. Approximately , to , puffins currently breed in eastern Canada, mostly in Newfoundland and Labrador. The population suffered substantial declines in the early s due to unregulated egg collecting and hunting on the breeding colonies. Atlantic puffins and their colonies are now protected, but they still face threats from climate change, such as warming the oceans and changes to their food availability.
This program was created to restore puffin populations back in to their historic nesting islands in the Gulf of Maine. Young puffins around 10 to 14 days old were transplanted from Great Island, Newfoundland where successful nesting had occurred and where around , pairs nest to Eastern Egg Rock in Maine.
